摘要:
运用坡面径流泥沙小区定位观测方法,2003年雨季对金沙江元谋干热河谷水土流失封禁管护措施的坡面产流产沙特征进行了对比研究.结果显示,封禁管护措施有较好的调节径流和减少土壤流失的作用,其产流量比干扰荒草地减少39.04%,产沙量减少50.26%;产流量与产沙量均与降雨量和最大10 min时段降雨强度呈显著幂函数关系,复相关系数分别在0.882和0.888以上;产沙量与产流量之间的线性关系显著,相关系数在0.929以上.
Abstract:
Characteristic of runoff and sediment production on slope land of enclosure for recovering vegetation is researched with the method of runoff plots observation in Yuanmou dry-hot valley of Jingsha River basin.The results show that enclosure for recovering vegetation is good at protecting water and soil from running off and erosion.The enclosure for recovering vegetation measure can decrease runoff amounts by 39.04%,and soil loss amounts by 50.26% than that on disturbed grassland.Runoff and soil loss have power function relationship with rainfall amounts and maximum rainfall intensity of 10 min and runoff has linear function relationship with soil loss amounts.
